### 5.2.4.5 Load Splitting

At the end of the Next-hop selection process, multiple routes may still remain. A router has several options when this occurs. It may arbitrarily discard some of the routes. It may reduce the number of candidate routes by comparing metrics of routes from routing domains that are not considered equivalent. It may retain more than one route and employ a load-splitting mechanism to divide traffic among them. Perhaps the only thing that can be said about the relative merits of the options is that load-splitting is useful in some situations but not in others, so a wise implementor who implements load-splitting will also provide a way for the network manager to disable it.
